siglk

siglk shortens links and builds email signatures, and counts the clicks on both. It runs on Cloudflare's edge, so a redirect resolves near whoever clicked it rather than near the server.

Working today: short links with custom aliases, expiry and per-domain codes; QR codes; email signatures rendered as email-safe HTML with a tracked link per person; a banner you can swap without anyone re-pasting their signature; signed webhooks; scoped API keys. Client libraries for JavaScript, Python, Go and Ruby cover links, keys and webhooks; they come with the invite, and the signature API is plain HTTP for now.

Two things so nobody is surprised. Bio pages are not built. And click counts fill in on a nightly rollup, so a link you just clicked reads zero until the next day.

Signup is closed while the invite flow gets written, so this is a waitlist.

I want people who would put a link shortener or a signature builder to work, ideally against their own product's API, and who will tell me plainly where it falls over.
